Uh, they don't seem to be sticking for me - which version is it that finally implements this, because I believe this one is second latest - I had some issues with the latest with my other phone and didn't upgrade this as I don't have space for alternative browser for pages that it affects so I'll upgrade if it gets fixed (I don't remember what it was, but I sent a report of it and saved a copy on my PC for later reference).
I'm baffled that it has taken insane amount of time to get it done right, it seems that opera didn't realize they have major portion of their users hackers and power users who value ability to modify their systems to fit their preferences way more than average user and dumbing down is shunned among them - most average users don't know me than two or three browsers if they even know they have a choice, and opera isn't one of them.
Back when dumb phones were all there was, except those rare Symbian or other lesser known ones and opera mini meant J2ME you used to know your target group - but then you went from unique to another chromium fork (and lost many of your users - I never upgraded to that and the last true opera on my PC is getting badly outdated) on desktop and that was when I got first sign that there has been a major shift in opera design philosophy.
